On 2015-10-12 (page 28), chris_c posted several improved syntheses which I have in my updated database, but which still haven't been updated on the web site:The first (this one) from 9 gliders. This new one is an improvement!The second (fox) from 9 gliders, one less than the new one.The fourth (by flops) from 11 gliders, one less than the new one.(However, in retrospect, your 8-glider synthesis of why not (see next paragraph) reduced this to 10, as 2 gliders can remove one bit. I hadn't noticed this before, but this post brought it to light!)

Also: The third one (hexapole) from 10 gliders by chris_c and later reduced to 9 by BlinkerSpawn on 2016-08-23, so the new one from 8 is better. (This improves 52 syntheses, and affects secondary syntheses for 5 others (all larger barber poles, and all pseudo-barber poles)!The fifth also from 12 gliders by Extrementhusiast on 2015-01-05.The sixth (why not) is the same one you posted on 2016-08-23.The seventh from 11 gliders by me on 2015-10-05 (page 27).

There appear to be two new soups to make this unnamed 16-bit flip flop (muttering moat 1 w/long middle arm): http://catagolue.appspot.com/object/xp2_3l04gl3z3201/b3s23 which suggest the following method, which might be plausible. Perhaps it could also be altered to make muttering moat 1, which has yet to emerge from any soup:

The second (quad) (originally 16 gliders by Dave Buckingham) was replaced by a 12-glider synthesis by Kayzan from a soup on 2015-12-28, reduced the next day to 11 by Extrementhusiast and 10 by me. Yours uses exactly the same mechanism.

The first (griddle w/tub and feather) was first synthesized from 77 gliders by Extrementhusiast on 2013-12-10, then the next day reduced by me to 74, and by Sokwe to 68. Yours is a dramatic improvement. Congratulations!

Very nice! All are new records except one. #2 (14.100) and #4 (14.352) can be reduced by 1 by combining two steps (rows 1+2). However, I had previously found a 10-glider synthesis of 14.352 on 2016-03-07 (row 3). There are now only two remaining 14-bit still-lifes costing 14 gliders: 14.618 and 14.191 (row 4). These syntheses also improve the derived 15.544, 15.873, 15.45, 15.70, 15.419, 15.624, 15.502, 15.503, 3 candelfrobras, 15.952, and 15.653 (row 5).
